Batch 4 and Clone batch vegetating. Learned a lot through this site. Last trouble was w/Tropical Cookie yellow brown curl treated w/flush & Domilite Lime & flush again from nuked tips. Only plant out of batch #3. Stuck an old ground meter which looked like 7.2 or so PH. Kept PH down to 6.5-7.0 range with watering but this plant reacted. Figured maybe meter saying too much PH so bought better PH meter for $34. Cheaper one flaked out after dropping into water second time. This read from this meter seemed to read higher than my usual citrus acid mix in tap so maybe PH always been a little higher from meter flaking out. So far all green in this batch and clone mix. Also using Touch of Balance mix with watering along with citrus acid to bring down the high PH 8.8 straight tap. Keeping room w/humidifiers average 45-55%. Figured light spread with extra cheaper lights that not quite as intensely bright as the pricier lights but act like a secondary room coverage. Think PH water the main ingredient that keeps the plant growing green. Haven't followed the EC or PPM numbers lately seeing the plants not showing reactions. Cut the fertilizer down to Dr. Earth organic but not on a certain schedule. First mix was watering water one time. Afterwards put mix in spray bottle that I use daily giving plants a drink couple times a day during the heat/light of day. Spray Dr. Earth maybe once or twice last three weeks. Thinking will keep to spraying a hit of Dr Earth fertilizer as I seem to see the plant could use a extra shot of nutrient. Tried the FoxFarm trio first couple plants and each time seeing an immediate action that questioned my dosage or their ratio so quit using fertilizer thinking keeping plant healthy first priority. Later read FoxFarm more good for quantity than quality so went organic from journal comment. Thinking good PH meter main tool needed to keep the plant green whether tap or distilled/spring water. Also have CO2 mushroom bag in flowering closet and now growing room. Have two fans in closet and standing fan pointed toward the light heat and above the leaf. Three cheap humidifiers keep closet/room humid enough or close enough average. Now keeping light close to 24" above plants, in closet have front high enough while back lights keep plant not quite directly underneath. Unless short like the tropical cookie. Keep with the same soil going from the Happy Frog mix to the Ocean Forest mix mainly from a recommendation from grower. Keeping with soil, light enough and light distance, perfect balance of water, CO2 extra, humid and fan blown ventilation in a closed room of central heat/cool. Added a artic water cool in corner of flowering closet since heat from light especially back two builds up especially when cover closet w/blackout curtain at the twelve hours light off. Heat does seem to effect the bud tightness. First couple batches of loose bud seem now to thicken up with better lighting far enough away so bud won't have to loosen up just to cool off. Last couple of Mimosa Bud have to use a saw to cut through the dried bud almost. Also got UV light to spotlight one plant last 30 minutes of light just to tweak the bud a bit. Getting down the basics of soil, water, light, & air makes the plant.
